Since 2006, GTA has marketed its Ho-Purdue Yeast, the most effective microorganism in the world for the production of cellulosic ethanol. GTA has helped companies and research groups worldwide to ferment their hydrolysates and help them to refine their processes for extracting sugars.

GTA continues to develop yeast technologies to allow the production ethanol twice as fast as its original yeast and capable of generating high value co-products such as various industrial enzymes during ethanol production from cellulosic feedstocks or from corn.

GTA will continue to improve its yeast technologies to produce new products using sugars derived from multiple cellulosic feedstocks (corn stovers, sugar cane bagasse, etc.) or from corn starch and cane sugars.
